S Models

Features of S Models

As the name implies, these are one-way clutch-type stepless speed changers that instantly go from zero to maximum RPM.Thanks to a creative construction that transmits rotation with a link mechanism and one-way clutch mechanism, they are compact and lightweight, their speed change ratio is a high 1:12, and they have no restrictions on mounting direction.

Options of S Models

Screw Control Devices

Use a Zero-Max speed changer equipped with a screw control device to change the speed if needing to make fine adjustments when changing the speed. These devices accept both S models and MS models. There is also an option available that involves modification of a model equipped with a standard level. When submitting an order, be sure to mark the screw control option after the Zero-Max selection.
